A while back, I bought a stereo microscope for soldering and fine work. It works great and has enough offset from the work to get a soldering iron into where it needs to go. I had to install a Barlow lens to do that. It even has a camera port...

I decided to buy the following: USB Digital Microscope 40X-1000X LED Camera for Android, Windows, Mac, & Linux I looked at the wifi microscopes, but I was afraid that with the wifi, I would need to install some custom app on the phone, that...

The Kickstarter iron looks interesting. However, with only 10W, I think there could be problems with soldering parts on large ground pads or 4-layer/6-layer PCBs. My iron has 80W and I use rather broad tips even for small parts (603), because...

I must admit I never considered using these electronic microscopes. For my setup something that goes straight down with a large screen probably won't too well. I have my soldering station inside of a roll-top desk to prevent the furry demons of...

I hear you! I am also in a similar count... But I have maybe been lucky that my eyes have not changed that much over the last many years, and my progressive lens are sufficient. And I also find it much harder these days to do much soldering...

I did see a post on a different thread in regards to this.. so I really appreciate that you took the time to help, enough said... Ahhh... that's where I went wrong. I knew Chris Miller's version was setup to compile with PlatformIO, but when...

I can understand the issues. I have had a few kickstarter projects that did not deliver. And I wondered about the horizontal orientation of the soldering iron. According to the comments, it is due to needing to put the camera and LED light on...

I just got notification of a new kickstarter project that ends on March 10th, 2026. It is a battery operated soldering iron that includes a camera and light. The soldering iron connects to your Android or Apple phone to give you an expanded...

Note, for various reasons, I have not been doing much with Teensys lately. Exactly where did you get the files from? Both Chris's original source and my updates have been mentioned in this thread. My Git repository based off of Chris's original...

I should be careful about talking too much of private meetings. But everyone here does deserve an update. If this seems a bit awkward, please understand I'm trying to balance community openness with private business discussions. Supply chain...

For most SPI devices, you can use any digital pin for the CS and/or DC pins. In the Teensy 3.1/3.2/3.5/3.6 processors, there are several special CS/DC pins that some of the display drivers use to provide micro-optimizations to speed up the...

A pre-designed board would be great, but if you use the Teensy 4.0, consider combining the following from Adafruit: Adafruit Teensy 3.2 feather adapter Adafruit Featherwing proto board Adafruit Teensy Feather adapter compatibility for Teensy 4.x...

Hey thanks!! That'll be a great help! -jim lee

Going to ditto that since I am New York as well - actually fairly close to Adafruit. And I agree with you about Protosupplies! Eyes are that good any more :)

Yes, I saw that. It is a shame, since I often bought Teensies from Adafruit (Adafruit being in NY is quicker for deliveries than Sparkfun in CO). Microcenter does sell the 4.1 (4.0 is currently sold out at the Cambridge MA Microcenter), but...

Another thing would be a Teensy 4.0/4.1 version of both prop shields (though it would be nice if the 4 pins on each end are lined up for 0.1" spacing). Obviously there would need to be changes, such as incorporating an I2S interface for sound...

I don't recall if I've replied to this before. For various reasons, I haven't been doing much with micro processors recently, but some thoughts on some useful boards: When I laid out prototype boards, some of the things that I put into the...

We decided to skip RT1170 and wait for NXP's next generation RT chip. PJRC signed a NDA with NXP, so if I knew anything about NXP's future plans I wouldn't be able to discuss details that aren't yet on their public website.

Between 2020 and 2022, I added this page about Teensy compatibility to the unofficial Teensy wiki project: https://github.com/TeensyUser/doc/wiki/Teensy-Compatibility I also created this google spreadsheet on various microprocessor layouts...

If you want to use batteries with the common 2 pin JST plug, I've used the Lipo Rider Plus from Seeed. You plug the battery into the JST plug. You get 5 volt, 2.4 amp power out of a USB A plug, and you can recharge the battery via a USB C plug...
